Methods, Models, Tools, & Databases

Powerful models, tools, and databases developed by EPA scientists are used around the world to evaluate air quality, study climate change, and predict how alternative policy scenarios would change the air at local, regional, and international scales.

EPA scientists have developed a variety of methods, models, tools, and databases to access how people and ecosystems are exposed to pollutants. These tools are used in risk assessments to develop strategies for protecting human health and the environment.

Sustainability is the key to creating a cleaner, healthier world. Methods, models, tools and databases developed by EPA exposure scientists help decision-makers find sustainable solutions for many of today’s environmental challenges.

EPA’s exposure methods, models, tools and databases are not only used across the country to ensure safe drinking water, they are also being used by researchers to identify emerging water-borne threats from chemicals, bacteria, viruses, and other contaminants.
